Eddie Flores is manipulative and goes about his way in getting the job done as a drug cartel operative would do. He has no problem doing anything for his Uncle Tito.
Eddie Flores had been working as an operative for his uncle Tito's drug cartel in Texas. Apparently, he and Riggs knew each other from there, but never really had that much close contact with each other.
Riggs and Murtaugh were working on a homicide case in connection with a narcotics trafficking case involving the Flores cartel, in which Eddie was in connection with. The homicide case involved a woman who appeared to have jumped off a building and onto a car, but along the way, it was narrowed down to that Eddie killed the woman pushing her off the building. While investing the case further, Riggs believes that the cartel he is investigating is in connection to Miranda's death, and that Eddie may very well have some part in her death, too. They go to find Eddie.
Eddie meets up with Riggs and Murtaugh. There, Riggs interrogates Eddie and tortures him to confessing to it. Just when Eddie was about to confess in his part of it and where Uncle Tito might be and how Tito was also the mastermind of it, he is then shot and killed by his uncle before anything else could be said.
